Hello,
Reaching out to see if anyone has developed an ad hoc historical tag browser that supports filtering, this would be coupled with a power chart to add pens. This is for a large system with a lot of pens being historized. I do not want to try and reinvent something if someone also has a solution.
Thanks,
Frank
Sounds like a good Exchange project 
I was working on this a while back, but it's only halfway there atm
Looks like it’s on its way with yesterdays change log update!
Technically that says Tag Browse tree, not Power chart, they are separate components. So maybe it is maybe it isn’t.
I forget if you can filter only tags with history with the tag tree 
if you can, then you could use this
I don’t believe the tag tree browser object would work for this application.
